  • Title: Treatment of gastroesophageal (acid) reflux with lansoprazole: an overview.
    Author: Dobrilla G, Di Fede F.
    Journal: Clin Ther; 1993; 15 Suppl B():2-13. PubMed ID: 7911400.
    Abstract:
    Despite the fact that reflux esophagitis is a multifactorial disease, inhibition of gastric acid secretion is the mainstay of medical treatment, both for moderate and severe cases. Antisecretory agents lower the acidity of the refluxate, thus decreasing its aggressive effect, which favors the mucosal healing process. The greater the acid inhibition, the greater will be the mucosal repair. This is the reason for a therapeutic gain for H2-receptor antagonists over anticholinergics and antacids, and for proton pump inhibitors over H2-receptor antagonists. The most recently developed proton pump inhibitor, lansoprazole, at doses of 15, 30, or 60 mg/day for 4 and 8 weeks of treatment, has proven to be significantly more effective than placebo (one multicenter study involving 292 patients) or ranitidine (three multicenter studies involving 653 patients) in terms of mucosal healing and symptom relief. In two comparative trials with omeprazole 20 mg vs lansoprazole 30 mg (in a total of 349 evaluable patients) healing rates were found to be similar, but in one trial the relief of heartburn proved to be significantly more pronounced in patients receiving lansoprazole who also used fewer antacids. The frequency of adverse events was comparable in the two treatment groups. Reflux esophagitis is a chronic condition and after stopping antisecretory treatment, including lansoprazole, most patients relapse in terms of symptoms and endoscopical lesions, which suggests the need for long-term treatment. However, a strategy for long-term control of reflux esophagitis remains to be defined (lower daily dose, alternate-day standard dose, or concomitant prokinetic drugs?). The safety of proton pump inhibitors given for prolonged periods also needs to be more thoroughly evaluated.
